I've noticed that in Lotus Notes hidden client, that the hidden views aren't shown by default but I can further hide them by using outlines. I also know that users can gain access to the hidden views by each of the following ways:
Right click on the database bookmark, "Application" -> "Go To" while holding CTRL+SHIFT
User opens database and goes to "View" menu and click on "Go To" while holding CTRL+SHIFT
Would there be some way to actually hide those views (aside from creating a reader list for each view)?
